Hi Christos,

Oh I see, you're totally right.

I was trying to use Clang to compile newlib, I wasn't aware that its

assembler didn't fully support the legacy ARM syntax - it was tryingto

parse it as unified syntax code. Using GCC it compiles just fine.

FWIW, there are a few issues to build newlib with clang for ARMv6-M andARMv7-(E)M, but I’ve been building and using it with several clangversions (with the help of a couple of patches) with no noticeableissues on baremetal targets.


Emmanuel.
